Abstract
The invention relates to an aluminum alloy for a rivet. The aluminum alloy comprises the following elements, by weight, 0.5-1.5% of Si, 0.2-0.8% of Fe, 1.0-2.0% of Cu, 0.5-1.5% of Mn, 5.5-6.7% of Mg, 0.1-0.5% of Zn, 0.05-0.29% of Ti, 0.5-1.0% of Co, 0.005-0.01% of Ba, and the balance Al. The shear strength and the heat resistance of the alloy obtained in the invention are high, the pressure processing performance, the machinability and the corrosion resistance of the alloy are good, the alloy can be subjected to heat treatment reinforced, and the plasticity of the alloy in states of annealing and quenching is good. The rivet prepared from the alloy can be riveted in 2-8h after quenching.
Description
Technical field
The present invention relates to a kind of rivet aluminium alloy.
Background technology
Existing rivet is the 2B12 aluminium alloy with the trade mark of aluminium alloy, and shearing resistance and 2A02 are suitable, and other performances are similar with 2B11, but rivet must rivet in the 20min after quenching, thus difficulty in process, thereby 2B12 aluminium alloy range of application is restricted.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rivet aluminium alloy.
For solving the problems of the technologies described above, the present invention realizes like this
A kind of rivet aluminium alloy, contain the alloying element of following weight percentage:
The aluminium of silicon 0.5-1.5%, iron 0.2-0.8%, copper 1.0-2.0%, manganese 0.5-1.5%, magnesium 5.5-6.7%, zinc 0.1-0.5%, titanium 0.05-0.29%, cobalt 0.5-1.0%, barium 0.005-0.01% and surplus.
The rivet preparation method of aluminium alloy may further comprise the steps:
(1), body of heater is heated to 400-450 ℃, add each raw material by prescription and carry out melting, after stirring,, behind the insulation 30-60min, do stokehold sampling analysis, adjustment, to guarantee that each constituent content is within allowed band through refining, slagging-off, degasification;
(2), cool to the furnace below 300 ℃, air cooling again with the speed of 30-50 ℃/h;
(3), quenching and timeliness: quenching 500-550 ℃, water-cooled, natural aging room temperature 96h.
Iron can increase DIMENTIONAL STABILITY and support performance, makes it at high temperature have high strength, hardness, but excessive iron and copper form the Cu2FeA7 component and reduces the required copper amount of annealing effect;
Silicon combines with iron, prevents that iron from combining the tensile property that reduces alloy with copper;
Copper can improve intensity, the hardness of aluminium alloy, but can reduce extensibility;
Cobalt can improve the intensity and the extensibility of ferruginous silumin;
Magnesium can improve the molten admittedly thermal treatment of X alloy and the intensity of the back alloy that quenches, and makes aluminium alloy at room temperature have higher intensity and extension performance, but can reduce tensile strength.
Manganese, barium can increase the recrystallize humidity of aluminium alloy, improve processibility, opourability and welding property and the resistance to corrosion of aluminium alloy.
The alloy that the present invention obtains has higher slip resistance and resistance toheat, and pressure machining characteristics and machinable performance and solidity to corrosion are good, heat-treatable strengthened, and plasticity is good under annealing and firm as-quenched condition.Rivet can riveted joint in 2-8 hour after quenching.
